In order to improve the influence of initial alignment error and the bias of measuring devices, the navigation accuracy was reduced with the increase of time and displacement on SINS/odometer integrated navigation, and the scheme for interactive electronic map matching algorithm modification was proposed. The right map matching algorithm was selected by changing the  attitude angle of the vehicle, and  accurately modifying the coordinate of the vehicle in turning. Besides, the initial alignment error and odometer coefficient error were modified by the position error at the same time to reduce subsequent navigation error. The simulation result shows that  the azimuth misalignment angle error can be convergented to two minute and the odometer coefficient error can be reduced to 0.08% quickly by the interactive map matching algorithm, which can satisfy the demand of navigation system. The vehicle driving experiment also shows that the proposed method is valid.
